Killer jellyfish-like creatures have washed up on several Cornwall beaches and people are issuing warnings issued over their deadly stings.

The Portuguese men o' war, which are made up of four different organisms working together, have been spotted on beaches near Newquay and in Bude.

Newquay Beachcombing shared the picture of what is also known as 'the floating terror' and people have commented that they saw a lot of them on Cornish beaches.

Last year, several specimens were spotted in West Cornwall. The Friends of Portheras Cove said on their Facebook page:

"They're back! Three Portuguese-Man-o-War have been spotted in West Cornwall during the past week, two by volunteers from FoPC (at Portheras and Penzance during beach cleans) and one at Hayle.

"Keep your eyes peeled if you are around the coast at the moment and you may spot one of these beautiful & fascinating hydrozoans. To the untrained eye they can look a bit like semi-deflated pink tinged balloons - but beware, they pack a powerful sting, so admire, photograph, but DO NOT TOUCH."

At the time, John Leech, CEO of Irish Water Safety, said: "The Portuguese man o’war floats on the surface of the water. It has a purple bladder filled with gas and it looks like a tall ship, which is where it gets its name.
